I'm struggling to make this scene to show the textures in the viewport, it was imported from this COLLADA file, and it renders ok in mental ray.

Activating textures (key 6) in the view port won't work, I think it is because it has three UV sets, the first one (map1) show the PNG texture but has no UV geometry, while the remaining two have some geometry in them but have no texture image.

This is how it looks rendered with mental ray, and textures activated in the viewport.

These are the three UV sets, what I want is to merge map2 and map3 into map1

  • What file format are the textures? What does it look like instead? Black? Gray? Wireframe? Green?

  • @mhlester The textures used in the DAE file are PNG with 32 bits per pixel (R8G8B8A8), I'm not sure whether those are converted to other format by maya

Select the uvs you want to merge over and go to

Create UVs - Copy UVs to UV set - Select the uv set you want to merge with.

If the uv set you're merging to already has UVs for the faces you selected, it will overwrite them.
